2 Claims.

The present invention relates to a tiltable dolly for carrying a lubricant drum or the like in an upright position.

One object of-the invention is to provide an improved dolly of the above character having a simplified, sturdy construction susceptible of exl tremely economical manufacture.

A related and more specic object is to provide such a tiltable dolly having greatly simplied, yet convenient means for carrying a lubricant drum or the like always in the upright position.

Further objects, advantages and features of the invention will become apparent kfrom the following description of an illustrative embodiment taken with the drawings, in which:

Fig. l is a side elevational view of a wheeled lubricating .apparatus constructed in accordance with the invention;

Fig. 2 is a fragmentary sectional plan view taken as indicated by the line 2--2 in Fig. 1; and Fig. 3 is a front elevational view. The illustrative apparatus shown in the draw-v ings includes a generally cylindrical container or drum lil adapted to hold a considerable quantity of lubricant which may be about 50 lbs., for example. A cover I2 may be secured to the top of the drum I by means of clamps I4 which are adjusted by means of wing nuts I6. A pump I8 for withdrawing lubricant from the drum l0 and supplying it under pressure is mounted at the center of the cover l2, the pump extending downwardly into the drum and protruding upwardly above the cover. The pump may be operated from a source of power such as an electrical outlet or a compressed air line.

The pump supplies lubricant under pressure to an outlet fitting 20 adapted to receive a lubricant hose (not shown) for conveying lubricant to a control valve and thence to machine parts which are to be lubricated. g

The dolly is provided with two wheels 30 carried rotatably at the opposite ends of an axle 32. The wheels comprise a pair of dished discs 34 secured together face to face and mounted on a tubular hub 35. The discs have rims 31 to sup- Y port a tire 33 made of rubber-like material.

Washers 4U are positioned at the ends of the hubs, and the hubs are secured on the axle 3'2 by means of pins 42. The ends of the axle are covered by hub caps 44.

The axle is carried at its ends just inside the wheels by a pair of side frame members 50. Each of the members 50 includes a'generally triangular plate or web 52 having a narrow reinforcing flange 54 extending inwardly along its entire periphery which extends around a forward apex, a rear apex, and an upper apex deiined on the plate. The front corners or apexes 56 of the side members 50 are rounded to form skids.

Each of the side members is reinforced by a rib 58 having an upper leg Ell welded to the inside of the portion of the flange 54 extending along the rear edge of the triangular web 52. The rib 58 has a lower leg 62 welded to the inside of the portion of. the ange 54 extending along the lower edge of the web 52. The upper and lower legs of the rib are connected by a portion G4 of the rib extending diagonally across the Web near its rear corner. The axle 32 extends through the rear apexes of the webs 52 immediately to the rear of the diagonal portions 64 of the ribs, and the axle may be welded to the diagonal portions which extend substantial distances along the axle, as shown. The diagonal portion S4 of each of the ribs is wider than the flanges 54 and the legs'58 and 62 are tapered outwardly from the width of the diagonal portion to the width of the anges 54.

A generally arch-shaped bar 10 interconnects the upper portions of the side members 50. The lower ends of the bar 10 are secured by bolts 12 to the outer side of the web 52 adjacent the upper portion of its front edge, the front edge of the bar and the front edge of the web being in the same plane.

The bar has a pair of lower legs 14 extending parallel to the outer surfaces of the webs 52 and a pair of oblique connecting portions 16 terminating at their upper ends in a short apex portion 18. A round handle carrying a grip 82 is bolted to the apex portion 'I8 of the bar and extends upwardly and rearwardly therefrom, the handle having a rearward bend .83.

The lubricant drum I0 is suspended between the upper ends of the lower legs of the bar 10 by means of apair of headed pivots 86 extending through a pair of generally triangular brackets 88 welded to the inner sides of the bar 10.' The pivots extend inwardly through U-shaped brackbrackets 90. The pivots 86 may be secured in place by means of transverse cotter pins |00. If desired, the U-shaped brackets 90 may be welded directly to the container l and in that case the band 92 may be omitted.

The lubricating apparatus, together with its dolly, is shown in its parked position in Figs. 1 and 3 of the drawings. The apparatus occupies this position during normal use. In this position the skids 5B rest upon the floor surface. The pivots 86, which support the lubricant container l0, are positioned approximately midway between the axle 32 and the point at which the skids contact the floor surface. Consequently, the lubricating apparatus is unusually stable in its parked position and there is little possibility of tipping over the apparatus during use. Because of its pivotal connection to the dolly, the lubricant container l0 is maintained in upright position.

When the lubricating apparatus is being moved from place to place, the dolly is tilted rearwardly by means of the handle 83 to disengage the skids 56 from the floor surface. The dolly may then be moved on its wheels with great facility. The lubricant container i swings on its pivots 86 to maintain the container in its upright position.

When the container li! is to be removed from the dolly, the apparatus may be tilted to either of two positions. The dolly may be tilted rearwardly on its wheels to lower the lubricant container tothe floor. surface at a point to the rear of Ythe wheels. The container may then be removed from the dolly by withdrawing the cotter pins 10D and the pivots 86. 1f the lubricant container is to be transferred to a low platform, or is to be placed adjacent a wall, it is more convenient to tilt the dolly forwardly on the skids 56, which are conveniently rounded for this purpose. The container l0 swings on its pivots E6 and is deposited on the floor surface at a point in front of the skids 56.

When all of the lubricant has been withdrawn from the container l0 by the pump I8, the container may be removed as described above, and exchanged for a full container. The container may also be refilled while it is in position on the dolly. Relling may be conveniently accomplished when the container is moved into either of its two positions on the floor surface, or into the parked position shown in the drawings.

The arched supporting bar l0 is made sufciently high and the pivots BE are located so that clearance is provided for the pump i8 to swing under the bar l0 when the dolly is tilted forwardly on its skids 5E. The containeris suspended high enough by the pivots so that clearance is provided between the axle and the lower part of the container when the dolly is tilted forwardly and backwardly.

As indicated by the appended claims, the essentials of the invention may be practiced without strict adherence to all of the details of the apparatus described above to explain and illustrate the invention.
